How to build a palette

  • Open Color Palette Generator.
  • Pick your base colour.
  • Click any colour to copy its HEX code.

What you get

  • Complementary: two opposite colours for strong contrast.
  • Analogous: neighbours on the wheel, calm and harmonious.
  • Triadic and tetradic: balanced sets of three or four colours.
  • A nine step scale from light to dark, great for buttons and backgrounds.

Using it well

Use one colour as the main, one or two as support and keep the rest for small accents. Check text with Color Contrast Checker.
